`vm-native-setup` printed those two lines with your SKU, or `sudo vm-native-cpuid enable <domain>` does the same on/off automatically around the guest (off for the cold boot, on once its network is up). The switch is host-wide: it applies to
every pinned guest at once, and a cold boot of any of them while it is on hits the enumeration
